No option to limit search to one file system

[FallenWarrior2k]

Many tools surrounding file system traversal include an option to disable crossing file system boundaries. find includes the -xdev option, which accomplishes this. fd, however, seems to lack such a feature at the present time. I've looked through the man page and the issue list and was unable to find anything relating to this.

Looking at the docs of the ignore crate, implementation should be quite simple as well: it only requires adding a call to .same_file_system(config.same_file_system) to the WalkBuilder, assuming a corresponding option same_file_system: bool is added to FdOptions, with corresponding changes in build_app() and main().

Thank you for your feedback.

Didn't know about the .same_file_system option, though.

Oh, sorry. Seems my search terms weren't precise enough.

However, since this uses an existing feature of the ignore crate, there shouldn't be any performance degradation if the option is not used, since the ignore crate defaults it to false anyway. Since it is basically just adding a public API for a feature that already existed, albeit unused, I wonder if you'd consider adding it.

If not, feel free to close this and the corresponding PR.

Ok, that sounds reasonable. I'll take a look at the PR soon, thank you.
